# [−][src]Macro mynewt::coap

    macro_rules! coap {
        (@none $($tokens:tt)+) => { ... };
        (@json $($tokens:tt)+) => { ... };
        (@cbor $($tokens:tt)+) => { ... };
        (@cbormin $($tokens:tt)+) => { ... };
    }

Macro to compose a CoAP payload with JSON or CBOR encoding. First parameter is `@none`, `@json`, `@cbor` or `@cbormin`, to indicate no encoding (testing), JSON encoding, CBOR encoding for thethings.io or CBOR minimal key-value encoding. JSON and CBOR encoding looks like: `{ values: [{key:..., value:...}, ...] }`. CBOR Minimal encoding looks like: `{ key: value, ... }`. Second parameter is the JSON message to be transmitted. Adapted from the `json!()` macro: https://docs.serde.rs/src/serde_json/macros.rs.html

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
